Exhibit 99.2

To Our Employees,

Last week we promised that we would keep you updated on progress toward the sale of the company to a company formed at the direction of investment funds (“Permira Funds”) advised by Permira Advisers LLC. This week we received an unsolicited, non-binding offer from Plato Learning to acquire RLI for $15.50 per share (which is $.65 per share higher than the Permira agreement). Our Board of Directors considered all aspects of this proposal and, together with our financial advisors, determined that the proposal could reasonably be expected to lead to a superior proposal. As a result, we have determined to engage in discussions with Plato. It is very early in the process and this does not mean we have reached any agreement with Plato. We will keep you informed as much as we can, as we will with the overall process. Attached is the press release issued today explaining this development.

These types of developments are not uncommon. Renaissance Learning is a quality company with outstanding products and people, so perhaps we should not be surprised that others view us as desirable. It is important to note that Board has not changed its recommendation; it continues to recommend that shareholders vote in favor of the merger with affiliates of the Permira Funds and the management team is moving forward on schedule with the process of closing the transaction with affiliates of the Permira Funds.

All of this can be a huge distraction. Our most important task is running our business and taking care of our customers. The best thing that we can all do is to focus on our jobs and keep our customers’ needs and our mission – accelerating learning – as our top priority. Our concern for the customer and for accelerating learning is what makes us unique and the quality organization that we are, and we need to maintain those high standards. I know I can count on all of you to do just that as we work through this process.

If you have any questions, please utilize the email box we established for that purpose – FAQ@renlearn.com.
